Using the triangle method, determine the resultant of vectors:
A = 15 units 20 degrees S of W
B = 20 units 50 degrees N of W
2. Corrected_text: Using the parallelogram method, determine the resultant of vectors:
A = 100 units 40 degrees N of W
B = 300 units 80 degrees N of E
3. Corrected_text: The equilibrant of Vector A = (-6, -2) is vector E. What is E?
